Notepad LOG facility

Here is what you can see in the Notepad HELP file:-(Yeah it's not a hi-fi tip)
(Just search for LOG there)

To append a log to a document

On the first line of a Notepad document, type the following extension at the left margin, making sure you use all uppercase letters and include the period:
.LOG

On the File menu, click Save.
Note

Every time you open this document, Notepad will append the current time and date to the end of the document, as specified by your computer's clock.

Now this is a very good feature...not requiring any programming or technical skills and helps to maintain records with correct date and time.
